Fixed inductors are components that store electrical energy in magnetic fields. They are also known as coils, chokes, or transformers. The purpose of a fixed inductor is to reduce unwanted electrical currents, or induce current in an electrical circuit.An inductor consists of a core, typically made of ferromagnetic material such as iron, and two or more turns of wire (typically copper). The number of turns and core type will determine the inductance of the inductor. Inductance is measured in Henries (H).Electrical current flowing through the wire will create a magnetic field, which generates a self-induced electromotive force (EMF). This EMF is opposed to the original impressed EMF. The result is that the current is reduced, causing the voltage drop to occur across the inductor. The amount of voltage drop reduction is proportional to the inductor\'s inductance.One of the most common uses of a fixed inductor is in a filter circuit. A filter circuit is used to reduce the magnitude of very high frequency signals, while allowing the lower frequency signals to pass through. The lower frequency signals are usually the ones desired in the circuit, and the higher frequency signals tend to interfere with the desired signal. By placing an inductor in the circuit, the higher frequency signals are attenuated, while allowing the lower frequency signals to pass relatively unaffected.Fixed inductors are also often used for impedance matching. Impedance is the opposition to current flow in an alternating current (AC) circuit, and is measured in Ohms (W). Impedance matching is necessary in order to properly transfer energy from one circuit part to another. Impedance matching is also used to reduce noise and reflections, which can lead to degraded performance of system components.Another main application of fixed inductors is in resonance circuits. A resonance circuit is an electric circuit designed to produce values of impedance or reactance at specific frequencies. When used in this way, inductors serve to store energy. The inductor will force an opposite force on the energy within the circuit, resulting in the resonance frequency occurring at a variable voltage. This type of application is often found in radio systems as well as audio noise reduction systems.Fixed inductors can also be used as sensing devices. When a voltage or current is applied to the inductor, the magnetic field created will cause a voltage to be generated in the coil, regardless of what it is connected to. This voltage can then be used to detect the presence of voltage and current. This application is commonly used in motion detectors, where an inductor is used to detect the presence of an object or person passing by.Fixed inductors are certainly an important part of many electrical systems, and no matter what application they are used for, they play an important role in ensuring proper and efficient electrical performance. Thus, the design and selection of fixed inductors can have a huge impact on the overall performance of a system, and should not be overlooked.
